Abstract (en)
[origin: EP2540366A2] A fuel deoxygenation system includes an oxygen permeable membrane (22; 22A) having a porous membrane (28; 28A) and an oleophobic layer (30). The porous membrane (28; 28A) has pores (32) that create a passage extending from a first side to an opposite second side of the porous membrane (28; 28A). The pores (32) have an average pore diameter less than or equal to about 0.06 microns. The oleophobic layer (30) and the porous membrane (28; 28A) allow oxygen to cross the oxygen permeable membrane (22; 22A) but substantially prevent fuel from crossing the oxygen permeable membrane (22; 22A). A method for removing dissolved oxygen from a fuel includes delivering fuel to an oxygen permeable membrane (22; 22A) and removing oxygen from the fuel using the oxygen permeable membrane (22; 22A). A method for modifying a surface of a porous membrane (28; 28A) includes depositing an oleophobic treatment agent on the porous membrane (28; 28A), removing solvent and heating the porous membrane (28; 28A) to form an oleophobic layer (30) on the porous membrane (28; 28A).
